To analyze cardiovascular and autonomic responses in elite youngsters, 13 male cyclists (15.43±0.51 years) performed a graded-test until voluntary exhaustion. Oxygen consumption (VO2), blood lactate (BLa), arterial oxygen saturation (SaO2), respiratory exchange ratio (RER) and rating of perceived exertion (RPE) were collected, while heart rate (HR) was registered for heart rate variability (HRV) analyses, looking for linear and nonlinear comparisons. Cyclists reached maximal exertion [RPE: 19.14±0.94; BLa: 8...

Performance threshold measures are used to predict cycling performance. Previous research has focused on long time trials (≥ 40 km) using power at ventilatory threshold and respiratory threshold to estimate time trial performance. As intensity greatly differs during shorter time trails applying findings from longer time trials may not be appropriate. The use of heart rate measures to determine 20 km time trial performance has yet to be examined. The purpose of this study was to determine the effectiveness of heart rate measures at ventilatory threshold (VE/VO2 Plotted and VT determined by software) and respiratory threshold (RER of 0...

Running economy (RE) and VO2max are important predictors of endurance performance for elite and semi-elite endurance athletes, with RE being an appropriate predictor in a homogenous running population. Altitude training has been observed to change RE (mL.kg(-1).min(-1)), and VO2max due to alterations resulting from acclimatization. This study tracked changes in RE and VO2max before and after a 10-day altitude training camp at 1828 meters. VO2max, RE expressed calorically, and respiratory exchange ratio (RER), were measured below anaerobic threshold (AT) to observe differences between pre-and post-altitude training...

Nasal and oral exclusive breathing modes have benefits and drawbacks during submaximal exercise. It is unknown whether these responses would extend to anaerobic work performed at high intensity. Nine individuals (males N = 7, females N = 2) performed a standard Wingate Anaerobic cycle test on a cycle ergometer under nose (N) and mouth (M) only respiratory conditions, performed in a counterbalanced order. A 2 (condition: nose, mouth) × 6 (time: 0-5 sec, 5-10 sec, 10-15 sec, 15-20 sec, 20-25 sec, 25-30 sec) repeated measures ANOVA was used to analyze the data with significance accepted at the p<0...

The synthesis of the mono NHC alane adducts of the type (NHC)·AlH3 (NHC = Me2Im 1, Me2ImMe 2, iPr2Im 3 and 3-d3, iPr2ImMe 4, Dipp2Im 10) and (NHC)·AliBu2H (NHC = iPr2Im 11, Dipp2Im 12) as well as their reactivity towards different types of carbenes is presented. While the mono NHC adducts remain stable at elevated temperatures, ring expansion reaction occurs when (iPr2Im)·AlH3 3 is reacted with a second equivalent of the carbene iPr2Im to give (iPr2Im)·AlH(RER-iPr2ImH2) 6. In 6, {(iPr2Im}AlH} is inserted into the NHC ring...

Treatment options for chronic hepatitis B (CHB) are pegylated interferon (Peg-IFN) in minimal-mild liver fibrosis and nucleot(s)ide analogues (NUC) in more advanced disease. Since little is known about their use in daily clinical practice, we conducted a multicentre prospective study to investigate treatment regimens applied to naïve CHB patients in real life. HBV-RER is an observational multicentre Italian network that collect clinic and virologic data of patients with CHB. Among the 2527 CHB patients seen during the study period (2009 - 2012), 502 patients started a first line antiviral treatment...

PURPOSE: Self-paced [Formula: see text] tests (SPVs) have shown to produce maximal oxygen consumption values similar to those from traditional protocols. These tests involve perceptually regulated stages in which subjects are asked to maintain rating of perceived exertion values of 11, 13, 15, 17 and 20 for 2 min each. What is not clear is how the last stage should be paced. The purpose of this study was to compare two different pacing strategies during the final stage. METHODS: Fourteen healthy, recreationally active individuals (11 men, 3 women) participated in a familiarization and two experimental laboratory visits...

In the present study we sought to investigate interactions between hypothalamic nitric oxide (NO) and ghrelin signaling on food intake and energy substrate utilization as measured by the respiratory exchange ratio (RER). Guide cannulae were unilaterally implanted in either the arcuate (ArcN) or paraventricular (PVN) nuclei of male Sprague-Dawley rats. Animals were pretreated with subcutaneous (2.5-10mg/kg/ml) or central (0-100pmol) N-nitro-l-Arginine methyl ester (l-NAME) followed by 50pmol of ghrelin administered into either the ArcN or PVN...

Nucleobindin-1 has high sequence similarity to nucleobindin-2, which encodes the anorectic and metabolic peptide, nesfatin-1. We previously reported a nesfatin-1-like peptide (NLP), anorectic in fish and insulinotropic in mice islet beta-like cells. The main objective of this research was to determine whether NLP is a metabolic regulator in male Wistar rats. A single intraperitoneal (IP) injection of NLP (100 μg/kg BW) decreased food intake and increased ambulatory movement, without causing any change in total activity or energy expenditure when compared to saline-treated rats...

This study examined the reproducibility of performance across 3 non-motorized treadmill (NMT) 5-km time trials (TT) and physiological, gait, and perceptual differences of running at 5-km pace for both NMT and motorized treadmills (MT). Ten male runners experienced in road racing that had never run on a NMT completed 3 TT to establish personal best 5-km pace. In a later session, participants ran at this pace for 5 min on the NMT while metabolic, gait, and perceptual measures were recorded and then ran at outdoor 5-km personal best pace on a MT at 1% grade (counter-balanced crossover design)...

ABA is involved in anthocyanin synthesis through the regulation of microRNA156, augmenting the level of expression of anthocyanin synthesis-related genes and, therefore, increasing anthocyanin level. Drought stress is the main cause of agricultural crop loss in the world. However, plants have developed mechanisms that allow them to tolerate drought stress conditions. At cellular level, drought stress induces changes in metabolite accumulation, including increases in anthocyanin levels due to upregulation of the anthocyanin biosynthetic pathway...

The potential of visible-near infrared spectroscopy to predict glucosinolates and total phenolic content in rocket (Eruca vesicaria) leaves has been evaluated. Accessions of the E. vesicaria species were scanned by NIRS as ground leaf, and their reference values regressed against different spectral transformations by modified partial least squares (MPLS) regression. The coefficients of determination in the external validation (R²VAL) for the different quality components analyzed in rocket ranged from 0.59 to 0...
